99 Ranger H/AC blower wiring

Anyone know where I can find the diagram for the blower. My blower quit last week with a blown fuse ,changed it and it worked till today. The fuse is good voltage on both sides,(checked) no voltage to motor ,(checked) no voltage to the resister,I removed the resister and it looked ok,( checked) no voltage to the blower switch on the dash. What could be the culprit??? Any suggestions appreciated,thanks

There are two fuses - one for blower motor relay coil, and another for the relay's switched contacts, so it depends on which fuse is blowing. I've sent a you a PM with a link to the wiring diagram.
